Flame segmentation type high-speed low-nitrogen combustor and combustion method thereof

The flame segmentation type high-speed low-nitrogen burner comprises an air box, a flame generating device is arranged in the air box, a gas box is arranged on the air box, the gas box communicates with the air box through a plurality of first spraying holes, and a contraction flow channel is formed in an end opening of the air box; a plurality of gas pipelines are uniformly distributed on the periphery of the outer side of the contraction flow channel, the gas pipelines are communicated with the gas box, nozzles inclining towards the contraction flow channel are formed in the front ends of the gas pipelines, a plurality of partition bricks are arranged in gaps of the outer side of the contraction flow channel, partition plates are arranged on the partition bricks, and the partition plates are arranged between every two adjacent nozzles respectively; according to the scheme, flames ejected by the burner can be radially and circumferentially divided and folded to form petal-like flames, so that the temperature
